A kidney receives renal plasma flow of \(600\ \text{mL min}^{-1}\). The filtration fraction is \(0.20\). Plasma glucose concentration is \(12\ \text{mmol L}^{-1}\). Glucose is filtered at the glomerulus, then reabsorbed sequentially: 99 % in the proximal tubule, 90 % of the remaining in the loop of Henle, and 80 % of the remaining in the distal tubule. Assuming no glucose is secreted, calculate the net amount of glucose excreted per minute (in mmol).

D. 2.9×10⁻³ mmol min⁻¹
